 Scene height? I want to spawn an emitter that fires lasers. The thing is that I want to spawn the pinned emitter from the very top of the map, so is there any function to get the height of the map?

Re: Scene height? The top of the map is Y-position 0.

Re: Scene height? Would this work for the position part?
HeightVar = SceneMan.SceneHeight
self.Pos + Vector((i-30),HeightVar)

Re: Scene height? Code: self.Pos + Vector((i-30),0) SceneMan.SceneHeight gets you the height of the map, but the 'zero' position starts at the top, and the Y-axis is upside-down (positive numbers down, negative above). Meaning, if you set the Y-position to be the scene's height, that would be the bottom of the map, not the top.

Re: Scene height? If I put self.Pos + Vector((i-30),0), would that change the Y position?

Re: Scene height? Vector((i-30),0) would have it at the scene's top. Having self.Pos added would have the y-axis the same as wherever "self" is on the y-axis.

Re: Scene height? In this case I use (i-30) as the x position because I spawn a lot of emitters very near with a for loop to reduce the amount of stuff written into the lua. If instead I do Code: Laser.Pos.X = self.Pos.X + (i-30)
Laser.Pos.Y = 0
, would that work?

Re: Scene height? If you giving it a position relative to another position, shouldn't you constantly just give it a Y value of 0?
Damnit, you beat me to it.

Re: Scene height? Quote: Vector(self.Pos.X + (i-30),0) Yah, pretty much. No need for extra variables though.

Re: Scene height? Y-position 0 should be visible, and would be the top-most pixel you can see.

Re: Scene height? About 50 pixels above 0. Not exactly sure the precise position.

Re: Scene height? This is odd. For some reason, I don't know where the emitters are spawning. I know they are being spawned, I can hear their emission's sound, but I don't know where they are. Code: function Create(self) -- placed this before to check if the particle was spawning. Lol
x = math.random(200)
if x > 1 then
print(x)
end
end
function Update(self)
for i = 1,60 do
Laser = CreateAEmitter("Beam")
Laser.Pos = Vector(self.Pos.X + (i-30),0)
MovableMan:AddParticle(Laser)
end
end This is my code so far, and my guess is that there isn't any problem at all. What could it be?
